Is this achievable using Canthoplasty? (Photos)

You have two issues: You have an inferiorly displaced lateral canthal angle. You also have upper eyelid ptosis. When the lateral canthus is altered with lateral canthoplasty, a tightening procedure, one can also raise the insertion of the lateral canthus. The upper eyelid is anchored to the orbital rim through the lateral canthus. Tightening this structure can also exacerbate the the upper eyelid ptosis. The surgeon operating on the lateral canthus therefore needs to be prepared to handle the additionally induced upper eyelid ptosis. There is no substitute for an in person consultation. Your eyes can be your best feature.

Hi, FancyThrottle. Thank you for your question and photo.
Eyelid ptosis repair can be done at the same time with a lateral canthoplasty operation. There are mainly two approaches in ptosis correction: Levator muscle repair and Muller muscle excision. I prefer levator muscle repair as I see that more consistent results are achieved.
